M.2 NVMe Male to PCIe 3.0 x4 Female Extension Cable

The M.2 NVMe Male to PCIe 3.0 x4 Female Extension Cable is a specialized interface conversion solution engineered to connect M.2 NVMe slots directly to standard PCIe 3.0 x4 interfaces . This cable enables the use of M.2 NVMe storage and other M.2 PCIe devices with motherboard PCIe x4 slots, providing flexible expansion capabilities for systems where direct M.2 slot availability is limited or where physical re-routing of the storage device is necessary for thermal or spatial optimization . Supporting PCIe 3.0 specifications, it delivers a data transfer rate of up to 32Gbps while maintaining backward compatibility with PCIe 2.0 and 1.1 devices . The cable assembly is constructed with impedance-controlled wiring and multi-layer shielding to ensure reliable signal integrity and minimize electromagnetic interference at high frequencies . Its flexible flat cable design allows for easy routing in space-constrained environments, making it ideal for custom builds, embedded systems, and expansion projects where traditional adapter cards cannot be used .
